CSS :
<style> .remove-uploadimg{ cursor:pointer;} .uploadimg{ display: inline-block; position: relative; } .uploadimg .remove-uploadimg{ position: absolute; font-size: 20px; top:-10px; right: -6px; } .remove-uploadimg{ width:30px; height:30px; background-color:#ccc; border-radius:50%; color:red; text-align:center; } .remove-uploadimg:hover{ text-decoration: none; }</style>
JS :
<script src="__PUBLIC__/js/mbUploadify.js"></script> <script> var upload1 = new mbUploadify({ file: document.getElementById('imgfile'), /*ajax 上传地址*/ url: "{:U('Upload/mbUploadImg')}", //上传进度 progress: function(){ $('#imgpath').show(); $('#imgpath').val('上传中...'); }, /*上传失败*/ error: function(file, msg){ document.getElementById('imgError').innerHTML = msg; }, /*ajax上传成功*/ uploadSuccess: function(res){ $('#imgpath').hide(); $('#imgpath').val(''); var data = JSON.parse(res); document.getElementById('img-data').innerHTML = '<span class="uploadimg">' + '<img src="'+ data.savepath +'" style="max-width: 300px;">' + '<input type="hidden" name="img" value="'+data.id+'">'+ '<a class="remove-uploadimg" title="删除">✕</a>' + '</span>'; } }); $('body').on('click','.remove-uploadimg',function(){ $(this).parents('.uploadimg').remove(); })</script>
PHP :
public function mbUploadImg(){ $upload = new Upload(); // 实例化上传类 $upload->maxSize = 5242880 ; // 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg'); // 设置附件上传类型 $upload->rootPath = './Public/'; // 上传文件 $info = $upload->uploadOne($_FILES['files']); if($info) { // 上传成功 $data['name'] = $info['name']; $data['ext'] = $info['ext']; $data['type'] = $info['type']; $data['savename'] = $info['savename']; $data['savepath'] = "/Public/".$info['savepath'].$info['savename']; $imgId = M('upload_img')->add($data); if($imgId){ $resData['code'] = 200; $resData['msg'] = '成功'; $resData['id'] = $imgId; $resData['name'] = $data['name']; $resData['savepath'] = $data['savepath']; echo json_encode($resData); return; } } // 上传错误提示错误信息 return $this->ajaxReturn(['code'=>400,'msg'=>$upload->getError()]); }
